Deftaudio's MIDI Breakout Boards Bring Easy 3x3 or 5x5 MIDI Support to the Teensy 3.2, Teensy 4.0
Offering three-in three-out on a Teensy 3.2 or five-in five-out on a Teensy 4.0, these boards make microcontroller MIDI projects simple.
Music specialist Deftaudio has launched a pair of MIDI breakout boards targeting the Teensy family of microcontrollers, offering five-in five-out on a Teensy 4.0 or three-in three-out on a Teensy 3.2.
Designed to interface a Teensy microcontroller with Musical Instrument Digital Interface (MIDI) accessories, Deftaudio's design offers considerable flexibility for handling multiple devices. "This can be your 5x5 MIDI interface, merger, splitter, filter, or whatever else you can imagine," the company explains of the larger Teensy 4.0-compatible variant. "This obviously requires programming Arduino framework with Teensy extensions.
"Power is supplied from Teensy, so no external power required. All Teensy pins are available on extra pin headers. This allows easy expansion if you're planning to add extra LEDs, buttons, OLED display, etc. You can do that without soldering. "
The two board designs are functionally equivalent, differing only in the number of inputs and outputs on offer and the performance of the microcontroller to which they attack. Both are also available as a bare PCB or as a complete kit of parts, lacking only the compatible Teensy board. Deftaudio has also produced optional acrylic panels and stand-offs as a basic case, designed primarily to sit above an optional OLED display board installed as an add-on.
All Deftaudio's designs are published to the company's GitHub repository under an unspecified licence; boards and kits, meanwhile, can be purchased via the Teensy 3.2 MIDI Breakout Board and Teensy 4.0 MIDI Breakout Board Tindie pages for between $9 and $38 depending on whether you need a bare board or a full kit with enclosure.
